Управление AC диммером через DimmerLink на Raspberry Pi 26 feb 2026 0 0 TL;DR: Прямое фазовое управление TRIAC с GPIO Raspberry Pi невозможно — джиттер ОС Linux составляет 1–10 мс, тогда как для управления TRIAC требуется < 100 мкс. Используйте DimmerLink как аппаратный к... ac-dimmer dimmerlink linux python raspberry-pi tutorial Leer más
Управление AC диммером через DimmerLink в Tasmota 26 feb 2026 0 6 TL;DR: Tasmota не может нативно управлять TRIAC диммером с фазовым управлением. Используйте DimmerLink как ведомое I2C/UART устройство. На ESP32 Tasmota: напишите 5-строчный скрипт Berry, который прив... ESP8266 ac-dimmer berry dimmerlink smart-home tasmota tutorial Leer más
DimmerLink не обнаруживается на шине I2C: режим UART по умолчанию 26 feb 2026 0 0 TL;DR: DimmerLink поставляется с завода в режиме UART . Команда i2cdetect не покажет адрес 0x50, пока вы не отправите команду SWITCH_I2C ( 02 5B ) по UART на скорости 115200 бод. Также добавьте подтяг... I2C ac-dimmer dimmerlink troubleshooting Leer más
DimmerLink Not Detected on I2C: UART Mode Default Issue 26 feb 2026 0 3 TL;DR: DimmerLink ships from the factory in UART mode . i2cdetect will not show address 0x50 until you send the SWITCH_I2C command ( 02 5B ) over UART at 115200 baud. Also add 4.7 kΩ pull-up resistors... I2C ac-dimmer dimmerlink troubleshooting Leer más
Tasmota AC Dimmer Control via DimmerLink 26 feb 2026 0 4 TL;DR: Tasmota cannot drive a phase-cut TRIAC dimmer natively. Use DimmerLink as an I2C/UART slave. On ESP32 Tasmota: write a 5-line Berry script that maps any rule trigger to an I2C register write at... ESP8266 ac-dimmer berry dimmerlink smart-home tasmota tutorial Leer más
Raspberry Pi AC Dimmer Control via DimmerLink 26 feb 2026 0 2 TL;DR: Direct TRIAC phase-cut from Raspberry Pi GPIO is not feasible — Linux OS jitter is 1–10 ms while TRIAC timing requires < 100 µs. Use DimmerLink as a hardware controller: RPi writes a brightness... ac-dimmer dimmerlink linux python raspberry-pi tutorial Leer más
AC Dimmer with Home Assistant: ESPHome and DimmerLink Guide 26 feb 2026 0 3 TL;DR: Two integration paths exist. Path A (standard ESPHome ac_dimmer platform) is simple but causes ISR/WiFi conflicts on dual-core ESP32. Path B (DimmerLink ESPHome component) offloads TRIAC timing...

ESP32-S2/C3/H2: AC Dimmer Doesn't Work on Single-Core ESP32 26 feb 2026 0 23 TL;DR: rbdimmerESP32 is designed for dual-core ESP32 (original and S3). ESP32-S2, C3, C6, and H2 are single-core. The library tries to isolate the dimmer task on a dedicated core — which is impossible... ESP32 ac-dimmer dimmerlink troubleshooting Leer más
